From January 2019, planes that are imported should be suitably equipped with indigenous navigation system GPS-Aided Geo Augmented Navigation (GAGAN), according to aviation regulator DGCA. The system was was officially launched in July 2015.

The national civil aviation policy requires all aircraft being registered in India from January 1, 2019 to mandatorily be GAGAN enabled. In tune with it, the Directorate General of Civil Aviation (DGCA) has said, “aircraft being imported for registration on or after January 1, 2019 shall be suitably equipped with GAGAN equipment”. The watchdog has included this provision in a new air transport circular on procedure for obtaining permission for import/ acquisition of aircraft.

GAGAN uses a system of ground stations to provide augmentations to the GPS standard positioning service navigation signal.
